CVE-2026-64508

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF Just-In-Time JIT compiler. The BPF JIT allocator reuses memory space, and when new code is written, an indirect jump into the new program can reuse a branch prediction left behind by an old program. This could allow an attacker to...

CVE-2026-43321

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. This vulnerability arises from the kernel's failure to correctly identify and mark active registers during indirect jump operations within the BPF program execution. An attacker could potentially exploit this to manipula...
